Hello,
I'm wondering whether its possible to parallelize a for loop on pointers
as in the following example.
AtomParam *ptrCour1;
AtomParam moleculeA[NBR_AT_M],*ptrLastElt_moleculeA =
&moleculeA[NBR_AT_M - 1];
for ( ptrCour1 = &moleculeA[0] ; ptrCour1 <= ptrLastElt_moleculeA
; ptrCour1++ )
{
tempory_molecule_1[ ptrCour1 - &moleculeA[0] ] =
(AtomParam)coor_mol2crys(*ptrCour1,vect_val_p.vect,vect_val_p.cm) ;
}
In serial mode it works well but if I do
#pragma omp parallel
{
#pragma omp for
for ( ptrCour1 = &moleculeA[0] ; ptrCour1 <= ptrLastElt_moleculeA
; ptrCour1++ )
{
tempory_molecule_1[ ptrCour1 - &moleculeA[0] ] =
(AtomParam)coor_mol2crys(*ptrCour1,vect_val_p.vect,vect_val_p.cm) ;
}
}
I get the following error:
/error: OpenMP for-init does not conform/
What should I do?
Thanks in advance,
Eric.
